Unsubstituted or substituted 5-iodo-6-amino-1,2-benzopyrones and their metabolites are potent, selective and non-toxic inhibitors and supressants of cancer growth and viral infections in a mammalian host. The compounds are particularly useful for treatment and supression of tumors and viruses associated with AIDS, herpetic episodes and cytomegaloviral infections. The methods of treatment of tumorigenic and viral diseases by 5-iodo-6-amino-1,2-benzopryrones and/or its metabolites are described.
